I’m excited to dive into one of Earth’s most fascinating and ancient life forms—mushrooms and fungi. Fungi have played a pivotal role in transforming our planet from a barren world into the vibrant ecosystem we know today. Long before plants dominated the landscape, Earth was a desolate place, primarily inhabited by microorganisms with little to no complex life. During the Precambrian era, the land was largely barren and devoid of vegetation (Beraldi-Campesi, 2013). However, everything began to change with the emergence of fungi. These ancient organisms, particularly through their vast mycelial networks, were key in breaking down rocks and contributing to the formation of soil. This vital process was a turning point that made the planet hospitable for plant life (Rosling et al., 2024).
What’s remarkable is that fungi didn’t just help plants take root—they formed deep, symbiotic relationships with them. These relationships enhanced plant growth and helped create the complex ecosystems that have since flourished across the planet. In many ways, fungi laid the groundwork for the rich biodiversity we see today. It’s humbling to realize that what we often overlook as simple mushrooms or molds are actually part of an ancient lineage that shaped life as we know it.
As you go about your day—whether sitting, walking, or even just breathing—consider that you are part of this ancient, invisible web that connects all life on Earth. Beneath your feet, an extensive mycelium network spreads through the soil, linking trees, plants, and countless other organisms in a grand, living tapestry. Every breath we take draws in spores, tiny reminders of our deep connection to the natural world. It’s easy to forget that this hidden network is always there, silently weaving together life in ways both seen and unseen. Whether we’re touching the earth, holding an object, or enjoying a meal, we are constantly engaging with this vast, interconnected web of life.
The resilience of fungi is another thing that really amazes me—they have been proven to have the ability to survive in extreme conditions, such as the vacuum of space. Resistant to high radiation and harsh temperatures, some scientists suggest that fungi could potentially hitch rides on comets and asteroids, seeding life on new worlds (Tetyana et al., 2020). Panspermia.
On a more grounded, localized level, growing mushrooms at home, for me, is a way to tap into this ancient wisdom and bring it into my daily life. Beyond their resilience, mushrooms offer practical benefits too. For example the first mushroom I’ve decided to grow, Lion’s Mane, is known to have many
benefits (click to expand).
Lion’s mane (Hericium erinaceus) has been the subject of various studies, with research suggesting several potential health benefits. Some of these have been supported by scientific evidence, particularly in areas related to brain health, immune support, and overall wellness. Below are some of the key health benefits of lion’s mane that have been studied:
1. Cognitive Function and Neuroprotection
- Neurogenesis: Lion’s mane is known to stimulate the production of nerve growth factor (NGF), a protein essential for the growth, maintenance, and survival of neurons. A study published in the Journal of Agricultural and Food Chemistry found that extracts of lion’s mane could promote neurite outgrowth, which is beneficial for brain function and repair (Mori et al., 2008).
- Memory and Cognitive Decline: Clinical studies have shown that lion’s mane may help improve mild cognitive impairment and memory. In a study conducted with older adults, those who took lion’s mane supplements for 16 weeks showed improvements in cognitive function compared to a placebo group (Mori et al., 2009).
2. Anti-Inflammatory and Antioxidant Properties
- Inflammation Reduction: Lion’s mane contains bioactive compounds that exhibit anti-inflammatory effects. A study published in Food & Function showed that lion’s mane could reduce inflammation by inhibiting the production of pro-inflammatory molecules.
- Antioxidant Effects: The mushroom is rich in antioxidants, which help neutralize harmful free radicals and reduce oxidative stress, potentially lowering the risk of chronic diseases like heart disease and cancer.
3. Immune System Support
- Immune Modulation: Lion’s mane has been found to enhance immune function by promoting the activity of the intestinal immune system. Research suggests that it can boost the proliferation of beneficial gut bacteria, which in turn supports the immune system.
4. Mood and Anxiety
- Reduction in Symptoms of Depression and Anxiety: Preliminary studies suggest that lion’s mane may help alleviate symptoms of anxiety and depression. In a small clinical trial, participants who consumed lion’s mane cookies reported reduced feelings of irritation and anxiety compared to a control group.
5. Gut Health
- Digestive Health: Lion’s mane has been shown to have protective effects on the digestive system, particularly in relation to ulcers. Animal studies suggest that the mushroom can prevent the development of gastric ulcers and protect the stomach lining.
6. Nerve Damage and Recovery
- Nerve Regeneration: Lion’s mane has also demonstrated the potential to promote nerve regeneration and recovery after injury. Animal studies have shown that the mushroom can speed up the recovery of nerves following damage.
Summary
While research into lion’s mane is still ongoing, studies have consistently pointed to its potential to support brain health, reduce inflammation, boost the immune system, improve mood, and aid in nerve regeneration. These findings highlight the therapeutic potential of lion’s mane as a natural supplement, but it’s important to note that more large-scale human studies are needed to confirm these effects and better understand its mechanisms.
The byproducts of growing them are also known to improve soil health. It increases nutrient content, and promotes beneficial microbial activity (Gao et al., 2010). By cultivating mushrooms, I can use the waste to enrich the soil in our garden, fostering a healthier environment for the plants and creatures that live there. It’s a small, yet meaningful, way of participating in the vast, interconnected web of life that fungi have helped build over billions of years.
Finally, a quick note on the aesthetics in the photo: I know the carpet and wall colors might stand out to anyone viewing the images below. Some sections of our home have a distinct, vintage vibe—complete with old-fashioned carpet and paint colors. This is because our home used to be a hotel, and some of the rooms that we rarely use, like this one, haven’t been remodeled yet and are almost like time capsules from another era.
